Specification of Letters late'nt, Pa'tgntgd J 113 17, 191.3,

' fimfl ieatien med April 2, 1913. Serial No. 758,693.

Be it known that I, 'MroHAnL M HALEQ citizenof .the. United States, residing at and useful Improvements in int-Chairs,- ot-which the following is a specification, ref- This invention relates 'to improvements rail joint chairs, and an object thereofis A- further-object of this invention is'the A still ffurtherobject of this invention is the provision of a joint chaireompri'smga. base plate" having an integral fish plate$ formed oni. one longitudinal edge thereof, and a clamping member also, comprising a base plate and a fish-plate, the base plate of the base plates being providedwith'registering notches for the reception of spikes or other fastening devices which are adapted to be driven into the ties.

Withthese and other objectsin-view, my invention consists in, certain novel construe tions', combinations and arrangementsof claimed and illustrated drawing, in which- I t Figure l is a top plan view of my invention partly'in section; Fig.i.2 is a section on the line 2 2 of Fig. .1; and Fig. 3 is a section on the line 3-3 of Fig. 1.

Referring more particularly to the drawing, the letter A represents the ties of-the track, B themeeting ends of a pair of rails and Gmy improved joint chair. The joint chair comprises a base plate 1,'which is of a length suitable to span a pair of the ties A, the base plate being formedon one longitudinal edge with inclined fish plate 2 which is adapted tooverlap one of the base flanges of the rail's'and rest against the webs thereof. The opposite longitudinal edge of in the accompanying the base plate liis formed with anupstanding flange 3 which terminates short of the ends of the base plate, the base plate being formedbet-weenthe extremities of the flange andihe'ends'of the plate with notches 4.-

The longitudinal edge otthe base plate'l upon which the fish plate is formed is also provided with a pair of laterally projecting lugs 5 havin gnotches Geach of the lugs being adapts to .rest u on one-of the ties.

The clamping member comprises a' base plate 8 andan inclined fish plate9, the base' plate 8 being adapted to-sl'idably rest uponthe base. platel between the flange 3 and the .lower extremityof the fish plate 2. The l .flange 9 is cut away at-its lower edge nean 1tS-6l'1dS,-&S at 10, and the base platev 8 13 provided with iiotchesall below the cut away portions of the flange, the notches 11 being adapted to register with the notches 4: of

theb'ase plate 1'. The webs on the ends 0fthe rail 13' are provides with openings 1-2 through which the laterally extending pins 13 formed on the inner face of the fish plate 2 area dapted; to enter, to prevent \rela-tive longitudinal-creeping of the rails. Spikes 13" or other suitable fastening devices are adapted.- to be passed through the notches 6 .and registering notches 4 and 11 to securethe joint chairto the ties and thereby prevent'longitudinal-go-r lateral movement of the rails with relation to. the ties.

' To securethe joint chair in position, the

base plate .1 isarra'nged upon the track to span a'pairof'ties, and the rails are then placed upon the base plate so that-the pins 13 engage in the openings =12 in the rails. a

The clamping member 7 is then 'engaged with the rail at one side ofthe base plate 1 so that the fish plate 9 engages the web of v the rail, and the clamping member is then moved longitudinally so that theba'se plate-J 8 thereof is engaged between the base late 1 and the bottom faces. of the 'rails,- until the notches 11 int-he base plate. 8 register with the notches 4 in the base plate 1 whereu iion the s ikes 13 are engaged in the notches and orced. into the ties to; maintain the several-parts 1n their "respective positions.

It will be seen that longitudinal or lateral movement of the joint chair is prevented by the engagement of the spikes 13' in the ties, and movement oft-he rails in any direction is also prevented by the engagement ofthe pins 13 in the openings 12 in the rails. The upstanding flange 3 on the base plate 1 serves as a guide for the elan'ip'mg member 7, and

also prevents lateral spreading of the sections of the joint chair.

From the above description taken in connection with the accompanyingdrawing, it will be seen that I have provided a joint chair which will scurelyhold the meeting ends of a pair of rails, and which also com prises a minimum number of parts, so that it may be cheaply manufactured. Having thus fully described my invention what I desire to claim and secure by Lettors Patent is: f 1. In combination with the meeting ends of a pair of rails, a joint=ehair comprising a base plate having a fishplate thereon for engagement with the base flanges on'one side of the rails, said base plate also having an upstanding flange formed on one longi-' tudinal edge, said-fiangecterminating short 'of the ends of the base plate, said base platebeing formed with notches between the extren'iities of said flange andthe'ends bf the base plate, a clampingonember comprising-a base plate adapted forslidable engagement between the firstmentionedbase plateand the bases of saidrails, said clamping memher being formed .with a fi sh plate adapted for engagement with the base'flanges on the opposite sideeot the rails,'tl bas plate of said clamping member being also pro-.

'vided with notches for registration with the Copies of this patent may be obtained for five cents each, by addressing the lower elige of the second mentioned fish plate being cut away at its opposite ends,

notches in the first mentioned base plate, as and for the purpose described.

2. In combination with the meeting ends of a pair of rails, a joint chaireomprising a base plate having a fish plate on one longi t-he'firstumentioned base plate and the bases .of said rails, said clamping plate being formedon one longitudinal edge with a fish plate adapted for engagement with the base flanges on the opposite side of said rails,"the

said second mentioned base plate being tions of said fish plate 'for registration with the notches in the first mentioned base plate, as and forjtne purpose described.
